Dahlia plant named &#39;Lomdahbrs&#39;

ABSTRACT

A new and distinct  Dahlia  cultivar named ‘LOMDAHBRS’ is disclosed, characterized by distinctive strong red flowers, a compact plant with a floriferous habit, and free branching. The new variety is a  Dahlia,  normally produced as an outdoor ornamental plant for containers or gardens.

LATIN NAME OF THE GENUS AND SPECIES

Dahlia hybrid

VARIETY DENOMINATION

‘LOMDAHBRS’

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a result of a planned breedingprogram directed by the inventor, Henry Lommerse a citizen of theNetherlands. The parent is an undistributed, unpatented proprietaryvariety Dahlia hybrid ‘25079’ and the pollen parent is theundistributed, unpatented proprietary variety Dahlia hybrid ‘25075.’ Thenew variety was discovered as a seedling in June 2006, by the inventorin a commercial research greenhouse in Mariahout, the Netherlands.

Asexual reproduction of the new cultivar ‘LOMDAHBRS’ by vegetativecuttings was first performed in 2008, at a research greenhouse inMariahout, the Netherlands. Multiple generations have since beenproduced and have shown that the unique features of this cultivar arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘LOMDAHBRS’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘LOMDAHBRS’ These characteristics incombination distinguish ‘LOMDAHBRS’ as a new and distinct Dahliacultivar:

-   1. Sturdy plant with a compact habit-   2. Strong red flower color-   3. Good branching characteristics-   4. Floriferous habit.

PARENT COMPARISON

Plants of the new cultivar ‘LOMDAHBRS’ are similar to plants of the seedparent, Dahlia hybrid ‘25079’ in most horticultural characteristics,however, plants of the new cultivar ‘LOMDAHBRS’ produce more flowers,bloom for a longer period of time and produce more ray florets than‘25079’. Additionally, plants of the parent variety are less sturdy andmore open then ‘LOMDAHBRS.’

Plants of the new cultivar ‘LOMDAHBRS’ are similar to plants of thepollen parent, Dahlia hybrid ‘25075’ in most horticulturalcharacteristics, however, plants of the new cultivar ‘LOMDAHBRS’ producemore flowers with a brighter red color, and foliage that is moreresistant to damage.

COMMERCIAL COMPARISON

‘LOMDAHBRS’ can be compared to the commercial variety Dahlia hybrida‘Singer’ U.S. Plant Pat. No. 11,315. The two varieties are similar inmany horticultural characteristics, including having a similar flowercolor. However, plants of ‘LOMDAHBRS’ differ in producing more branches,and a more compact plant shape than ‘Singer.’ Additionally plants of‘LOMDAHBRS’ begin flowering earlier from a rooted cutting than ‘Singer.’Flower form is also different between the two varieties, with‘LOMDAHBRS’ producing a more spherical, less flattened flower form.

The new variety can also be compared to the commercial varietyunpatented Dahlia variabilis, ‘Dapared’. U.S. Plant Pat. No. 17,143.Dahlia ‘LOMDAHBRS’ and Dahlia ‘Dapared’ are similar in manyhorticultural characteristics, including a similar flower color.However, plants of ‘LOMDAHBRS’ are more vigorous, produce more flowersand branches per plant, and larger flowers than ‘Dapared.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘LOMDAHBRS” grown in a outdoors, in Mariahout, theNetherlands, in a commercial 20 cm container. Age of the plantphotographed is approximately 70 days from a rooted cutting. Thephotographs were taken using conventional techniques and although colorsmay appear different from actual colors due to light reflectance it isas accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart except where general terms ofordinary dictionary significance are used. The following observationsand measurements describe ‘LOMDAHBRS’ plants grown outdoors, in theground during the Summer months in Mariahout, the Netherlands. Thegrowing temperature ranged from 16° C. to 27° C. daytime and 16° to 18°C. at night. One treatment of the growth regulator daminozide 85% at arate of approximately 0.1%, was applied at approximately 2 weeks afterplanting the rooted cutting. Measurements and numerical values representaverages of typical plant types.
